Synthetic aperture radar (SAR) has the unique ability to precisely measure slow surface motions, and this capability is widely used in many applications. Most of these methods were developed in the last two decades, while the increase of available SAR data in recent years has allowed the use of these approaches in various scientific and commercial projects. Based on our long experience and 16 years of cooperation in the Dragon project, supported by bibliometric analysis, we argue that the recent advances in surface motion from SAR can be divided into three periods: data sparsity, availability, and ubiquity. The methodological development, however, antedates this progression. Therefore, we provide an overview of the methodological development of surface-motion estimation from SAR and discuss commercial advances in the field.

SAR表面运动估计的范式变化：中欧龙计划16年合作的经验教训

合成孔径雷达 (SAR) 具有独特的精确测量慢速表面运动的能力，这种能力被广泛应用于许多应用中。这些方法中的大多数是在过去的二十年中开发的，而近年来可用 SAR 数据的增加使得这些方法能够在各种科学和商业项目中使用。基于我们在 Dragon 项目中的长期经验和 16 年的合作，在文献计量分析的支持下，我们认为 SAR 地表运动的最新进展可以分为三个时期：数据稀疏性、可用性和普遍性。然而，方法学的发展早于这一进展。因此，我们概述了 SAR 表面运动估计的方法论发展，并讨论了该领域的商业进展。
